Cover a clean, dry bowl in plastic wrap to protect it. Tape to the insides if necessary with a removable tape (like painter's tape).
Tear or cut several pages of newspaper into squares.
Place a layer of Mod Podge on the outside of the plastic wrap.
Lay down pieces of newspaper down on the surface of the bowl and smooth with a paintbrush covered in Mod Podge. Press the paper down and brush right over the top.
Continue overlapping newspaper pieces and applying with Mod Podge until the entire bowl is covered. Apply a second layer of newspaper for more rigidity. Wrinkles will form, but don't worry about those. It's part of the character.
Apply a layer of Mod Podge and let the entire bowl dry on your work surface, even overnight if you're in a humid area.
Once dry, remove the layer of plastic wrap from the bowl mold, releasing the bowl. You might have to twist a little bit. Remove the plastic wrap from the paper mache.
Use the bowl mold as a template to trim the edges of your newspaper bowl with scissors.
Paint the inside and outside of the bowl with acrylic paint if desired.
Paint a layer of Mod Podge on both the inside and outside of the bowl; let dry and apply a second coat. Let dry completely before using.
